On our go live date, BT had forgotten to book the job in. If it had not been for intervention from Opus, we would have been without phones all weekend. I cannot commend and thank them enough.

If you are looking for a cost effective alternative to ISDN which enables all of the benefits of IP communications, such as flexibility, resilience and saleability then you need to consider SIP (Session Initiation Protocol) trunking.
A SIP connection is a service that connects a company's PBX (Private Branch Exchange) or SIP enabled equipment to the existing telephone system infrastructure via the Internet using the SIP VoIP (Voice over IP) standard.
Using a SIP connection can simplify administration for your organisation as the SIP connection typically will use the same Internet connection that is used for normal data.
You can use SIP to give you resilience so that in the event of a disaster where your ISDN30 link goes down you can rapidly switch to using your SIP internet connection or you can simply replace your ISDN30 with SIP trunks with their inherent multi-connection resilience. If for any reason you cannot access your offices due to fire, flood or something as simply as a power cut, the flexible nature of SIP trunking gives you the capability to switch your operations quickly to another location or initiate home working.
Unlike ISDN30 which has some minimum channel restrictions, we can enable exactly the number of virtual lines that you require now and easily add extra SIP trunks as business grows, so you are only paying for what you need at any time.
Using SIP trunks you can keep your phone number if you move anywhere within the UK, because your phone number is attached to an IP address not a physical telephone line.
